PLANE.

SPECIFICATION forming part of Letters Patent No. 279,885, datedJune 19,1883. Application tiled February 24,1883. V(l\'omodel.)

To all whom, t may concern/.-

Be itknown that we, SoLoN R. RUs'r and AR- TEUR E. RUST, citizens of theUnited States, residing at Pine Meadow, in the county of Litcheld andState of Connecticut, have invented certain new and useful Improvementsin Beneh-` Planes; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in Io the art to which it appertains to make and use thesame.

Our invention relates to improvements in what are termd blo ck-planes ,7and the obj ect is to produce a Vplane in which the bottom or face ofthe plane can be easily adjusted to the ,iron by means of a hinge motionin back part of plane, and to produce a clamping-bar with central pointbearing against a central bear-- ing, cast solid with the frame withouta core,

2c and to form a cheek-nut and knob on the adjusting-screw, and also tosimplify the general construction and operation. 4

Our invention consists in constructing a block -plane so that the planebit or iron which projects through the mouth or opening can be adjusted,as desired, to form an open or close mouth, andto suit the nature of thework to be performed in an expeditious man- Y ner. The bottom or face ofthe plane is hinged 3o to the rear part ofthe skeletonframe or stock,

and is adjusted by means of a iiat wheel on an adjusting screw or stud,and fitting with one side under lugs cast on the frame at its front end,and with the other side against two cross- 3 5 bars, also east on saidframe, v A check-nut and knob on saidadjusting-screw secures and locksthe wheel in place. .n

It also consists in holding the bit or planeiron in vplace by a screw inthe clamping-bar 4o against said iron, while said clamping-bar bearswith its upper side against a central point east solid in the frame, andwhich forms a fulcruin for it. The lower side f the planeiron restsagainst two cross-bars, also east sona with the name.

It also consists in adjusting the open and close mouth without a movablefront piece;y

and it also consists in the construction and arrangement of certainparts of a plane, as will cifically pointed out in the claims, referencebeing had to the accompanying drawings and the letters of referencemarked thereon.

Like letters indicate like parts in the different figures of thedrawings, in which- Figure l represents a side elevation of the plane.Fig. 2 is a top view of the same. Fig. 3 is a longitudinal sectionvofthe same. Eig. 4 is a top view of the bottom of the plane. Fig. 5-is alongitudinal section of the same. Fig. 6 is a longitudinal section ofthe frame. Fig. 7 is a top view of the same. Fig. 8 is an end view ofthe same.

In the drawings, A represents the skeleton frame or stock,consisting ofthe side pieces, a a, connected by a series of cross pieces or bars, oneof which, b', forming the hinge-pin for the bottom B, and another one,c, being the central bearing for the clamping-bar C; The bottom isprovided with a lug, b, into which the 7o bar b fits, and is held inplace by a clampingplate, b, and screw b. At the forward end of theplane is arranged a screw, D, upon which a dat milled wheel, E, isscrewed, tting with its upper surface under lugs d, cast 7 5` on eachside or wall of the frame, and with its lower surface bearing on twobars, e and f. A milled clamping-screw or cheek-nut, F, secures thewheel in its locked position. By this arrangement the bottom or face ofthe 8o plane can be adjusted to a nicety to the plane iron or bit. Thebars c and f are provided with raised parts c and f to form a moreperfeet adjustment for the wheel. The clampingbar C secures thefplaneiron or bit G in posi- 8 5 tion by means of a screw, g, which forces thebar C against a central bearing, h, on the bar c, cast solid with theframe and without the use'of a core. The lower side of the plane iron orbit rests on two cross-bars, fi 7c, also 9o east on the frame. Thebottom is provided with two curved ears, Z, which fit closely intocorresponding recesses formed in the frame, and they serve to hold thebottom in position and prevent any lateral movement. `It will be readilyseen that by screwing the face or bottom close down or tight, andsetting the iron or bit, an open mouth is formed; and by letting theface or bottom down and then setting the iron or bit a very close mouthis ob- Ioo l tained. A much greater pitch is also obtained by having theadjustment at the 'front end of the plane than if on the back under thecutting-iron, which is a great advantage, as it makes a much smoothercut. The bit can be adjusted nicely to coarse or line work.

Having thus described our invention, what we claim, and desire to secureby 'Letters Patent, is-

1. In a plane, a fiat wheel, E, for adjusting the size of the throatofthe plane, and having its bearings on the bars e f and, under lugs d,as shown, in combination with ascrew, D, secured to the hingedbottoni B,substantially as specified.

2. The adjustable bottom B, hinged at the rear end of the frame A bymeans of a bar, b, having bearings in a lug, I), and held by aclamping-plate, b, and adjusted at the front end by a screw, D, andwheel E, in the inanner shown and set forth.

3. The frame A, provided with a bai', c, having a central bearing, h,for forming a i'ulcruni for the clamping-bar C, provided with a screw,g, by which the bit G is held in place in the plane, substantially asspeciiied.

4. The skeleton frame A, provided with bars e f and lugs d d, formingbearings for the wheel E, a bar, c, having central bearing, Il., againstwhich the clamping-bar C bears, and the pivot-bar b, forming thehinge-bar for the adjustable bottom, and all cast in one piece, as setforth.

5. rlhe method of and means herein d cscribed for adjusting the bottoniB to form an open provided with curved ears Z, fitting intocorresponding recesses in the sides of the skeleton frame A, with a bit,G, held in place by a clamping-bar, G, and thumbscrew g, the stationaryscrew D, and wheel E, for adjusting the bottom, substantially asdescribed, and for the purpose set forth.

8. The plane herein described, consisting of the skeleton frame A, towhich the bottom. Bis hinged adjustably, in combination with a screW,'D,clamping-wheel E, check-nut F, bit G, clanipingbar C, with screw g, andCentral beaiiiigpoint, all constructed and ar- ,ranged substantially asspecified.

In testimony whereof wc hereby afiX our signatures in presencel of twowitnesses.
